微信小程序WeUI中half-screen-dialog底部弹窗相关问题

需求：
如图需要从页面底部弹出一个弹框，弹框里的内容超出最大高度时，可以滚动。

问题：

1. 原生的组件关闭图标在左侧，需要通过样式改到右侧
2. 原生的组件底部有footer按钮区域，需要通过样式隐藏掉
3. 在弹框里使用区域滚动通过scroll-view 设置纵向滚动并给最大高度
4. 设置title
5. half-screen-dialog如果在子组件中引入，需要在pages父组件中的css文件里修改样式。在子组件中修改不生效

代码：

index.json

{
  "component": true,
  "usingComponents": {
    "compute-cart": "/components/computeCart",
    "mp-half-screen-dialog": "weui-miniprogram/half-screen-dialog/half-screen-dialog"

弹窗样式只能写在pages父组件中

/* half-screen-dialog ui组件样式只能写在pages里 */
 .type-dialog .weui-half-screen-dialog__ft {
  display: none !important;
}
.type-dialog .weui-half-screen-dialog__bd {
  padding-bottom: 20px;
}
.type-dialog {
  padding: 0;
}
.weui-half-screen-dialog__hd {
  padding: 0 32rpx;
}
/* 隐藏更多按钮避免关闭点击偶尔失效 */
.weui-half-screen-dialog .weui-icon-btn_more{
  display: none !important;
}
.weui-icon-btn_close {
  position: absolute;
  right: -680rpx;
}
.weui-half-screen-dialog__hd__main {
  padding-left: 0 !important;
}
